Not in a good position to say no

MacKenzie felt she had little choice, she was naked, Willow did look the part of a sexy scientist in her white lab coat and MacKenzie was still trapped in the arms of Bonnie the skeleton. Willow seemed to be her only chance of escape, and had managed to turn off the mechanism which was making Bonnie vibrate in an exciting, but embarrassing way - 'OK - I will play - what do you want me to do ?'

'First let me put these on you', Willow said, taking one of the chains which hung from pulleys on a rail in the ceiling, and closing a cuff at the end of the chain around MacKenzie's right wrist. The click as it closed sent a thrill through MacKenzie. Was this really going to be a rescue or just a change of ownership ?

'Are the chains really necessary ? - I will do what you want' MacKenzie asked.

'We have two girls and one item of clothing, which I am wearing, and I intend that it should stay that way' said Willow firmly. 'If I give you too much freedom you might be tempted to try to take the lab coat off me, and if you failed then I would have to punish you'

As Willow closed the other cuff around MacKenzie's left wrist MacKenzie felt a mixture of excitement, nervousness and relief. It was a good thing Willow was in charge, she would never have thought of that, and prospect of being able to get her hands on the lab coat was to tempting that she might have done something foolish. Willow was wise as well as sexy. She almost purred as Willow stroked her back in the process of disengaging the skeletal hands from behind her back.

Willow started to pull on a chain and MacKenzie' hands started to rise into the air. As she had not been expecting this she lost her balance and fell forwards onto Bonnie again, trapping her left nipple. Now MacKenzie's hands were restricted by the chains, and she could not free her nipple, and had to ask for Willow's help.

Willow's hands felt good on MacKenzie's breast, and she gasped with a mixture of pain and pleasure at the sensation as her nipple was freed. It was also embarrassingly intimate, and MacKenzie hoped her friend was not too upset by having to help her in this way.

Willow resumed her pulling on the chain and MacKenzie was able to kneel more upright. Once MacKenzie was kneeling astride Bonnie with her hands above her head, Willow was able to approach her safely and with arms around MacKenzie's waist and torso, support her as she dismounted from Bonnie. Willow's hands cupped the undersides of MacKenzie's breasts as she did this and although MacKenzie was grateful for the support she felt that she could probably have managed without the support, and was sorry to have put Willow to the extra trouble.

Once MacKenzie was standing upright, with her hands raised as far above her head as they could be while she was still able to have her heels on the floor it was, apparently, necessary for MacKenzie's measurements to be taken.
